Abstract: A host connected to at least one data network has a processor having a plurality of cores, and a memory. A network interface controller is coupled to the host, and configured to transmit and receive data packets via multiple distinct physical ports. The host and the network interface controller are cooperative upon receiving a packet for storing the packet in a receive buffer of the memory, deciding in the host, responsively to a destination identifier in the packet, to forward the packet from the host to the at least one data network via another one of the physical ports, and selecting one of the cores to perform a send operation.

Abstract: Serialization and deserialization of an object are performed by transmitting metadata and addresses of data members in a byte stream through a data network, receiving the byte stream from the data network, defining a container for the object, obtaining the addresses of the data members in the first memory from the input byte stream, applying direct memory access (DMA) or remote direct memory access (RDMA) to read the data members using the obtained addresses, and writing the data members into the container to create a new instance of the object.

Abstract: A method for communications includes receiving in a network interface controller (NIC) of a host computer incoming data packets from a network on multiple active rings. An average throughput rate of the incoming data packets is measured over the active rings. For each ring among a plurality of the active rings, a respective throughput rate of the incoming data packets on the ring is measured, and a respective interrupt moderation parameter of the ring is set responsively to a comparison of the respective throughput rate on the ring to the average throughput rate. Interrupts are issued from the NIC to a central processing unit (CPU) of the host computer in response to the incoming data packets on the ring at a rate determined in accordance with the respective interrupt moderation parameter.
